Why does Fergie look so old?

Why does Fergie look more than a decade older than her chronological age despite having had what many believe to be plastic surgery? She freely admits to having used crystal meth in the past. What does crystal meth do to the skin? Bad, bad things. According to one ex-user, Methamphetamine caused their skin to become more fragile and apt to break out and swell. The drug consists of many toxins, which are excreted through the skin, in the process making it look older.
